this is a cj with stock yj springs SOA. from rocky-road.com it seems to me the yj springs flex pretty good. now this is with some premium shocks i assume.

this made me think, what if i put stock yj springs, SUA, but to obtain my 2.5 inch lift i make custom spring hangers that would end up with the mounting hole 2.5 inches lower than the stock mounting hole. I would also buy front lift shackles to make the front and rear of the leafspring even.

i am in a welding class every day for about 2.5 hours in school, so i can weld up the spring hangers no problem

if project turns out like i hope it will be an 81 cj5 with 283 chevy, nv3500, and dana 300. money will only allow me to run 31's for now which is why i would like to go budget. then two or three years down the road i can grind off my homemade hangers, get 33's and a 4 inch lift

tell me what you guys think about this, because besides the rather large spring hangers, i cant really see any problems with this scenario

YJ springs are softer than CJ springs, they ride flat while the CJ springs have a little bit of arch to them. take that into consideration. plus just like shackle lifts, if you only drop four [instead of all eight mounts] you will only gain half of the amount you drop it.

"why do you want your jeep to flex?" ...umm, the more flex the better. as long as the tires are in contact with the ground and have traction, you can keep moving.

If stock YJ springs are flatter, won't you LOSE lift by just swapping them out for your arched CJ springs?

I understand that they are preferred when doing and SOA to keep your height down and flex better, but I don't see how they could lift your CJ by keeping them spring under unless you also lower your fixed mounts and add longer shackles?

iron maiden, that is exactly what i am saying. i know that my old cj springs are worn out and i am wanting to find a good set of yj springs, because they are cheap and i hear they ride good, and then to gain my lift i would lower my fixed mounts and add longer shackles, at all leaf springs. it is basically the same ideah of putting a block between the axle and leaf spring on SOA, but it would be like putting the block between the frame and spring hanger, and then adding longer shackles to complete my lift. or i could even lower the point in which my shackle attaches to the frame

I've seen a 7 lifted with stock YJ springs and a SOA and it works great and rides nice on 33's.You have to change the spring hanger and perch because of the width and SOA, move the shackle mount forward 1 hole because thier longer too.I plan on doing same for my 7 soon,we need lots a flex out here on the rocks

He's not talking SOA.

He wants to move the spring hangers down and keep it SUA, which IMO is not a good idea.
